Patent number: 8542955Abstract: A gas detection system is provided for identifying a gas. The gas detection system includes a sensing module with a hollow chamber enclosed by a chamber housing. Additionally, the sensing module includes an optical sensing fiber positioned within the hollow chamber. The optical sensing fiber includes a gas sensor including a fiber Bragg grating positioned at a grating location along the optical sensing fiber, and a sensing layer affixed to an exterior surface of the optical sensing fiber at the grating location. After the gas is directed into the hollow chamber, the sensing layer and the gas exchange heat energy, based in part on a heat transfer coefficient of the gas. The exchange of the heat energy induces a shift in a Bragg resonant wavelength of the fiber Bragg grating which exceeds a threshold shift required for detection, where the shift is used to identify the gas.Type: GrantFiled: October 28, 2010Date of Patent: September 24, 2013Assignee: General Electric CompanyInventors: Hua Xia, Renato Guida, Juntao Wu, Axel Busboom, Aniceto Bantug, Pramod Chamarthy

Publication number: 20110052115Abstract: A fiber optic sensor system employs at least one light source that operates to generate light having one or more desired wavelengths. A first optical fiber based sensor transparent to a desired light wavelength operates to sense a magnetic field emitted from a predetermined electrical conductor or a current flowing through the electrical conductor. A temperature sensor that may be another optical fiber based sensor operates to sense an operating temperature associated with the first optical fiber based sensor in response to the light generated by the light source. Signal-processing electronics adjust the sensed current to substantially compensate for temperature induced errors associated with the sensed current in response to the measured operational temperature of the fiber optic sensor.Type: ApplicationFiled: August 27, 2009Publication date: March 3, 2011Applicant: GENERAL ELECTRIC COMPANYInventors: Boon Kwee Lee, Renato Guida, Juntao Wu, Sebastian Gerhard Maxim Kraemer, Sachin Narahari Dekate
